Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
Can you please indicate the engine code? (as there are many variants on these systems: regular injection, fsi etc.. )
do you have any other warning lights (like the ESP light)?
What was checked or replaced yet?
Customer: replied 2 years ago.
I stated the engine codes and no warning lights are on before the gearbox and clutch changed
Expert:  Billy replied 2 years ago.
Hello again,
By engine code, i mean the code that is on the engine block, or on a plate inside engine bay. This should be a three or four letter code (ex: AWP, BAS. CBAA etc...) I need this to get specific info on your engine.
Were the O2 sensor and its wiring checked? (as due to the gearbox replacement, someone could have damaged the wiring)
